PA09XX Transformer Winding Configuration Matrix

The following is a matrix of the winding configurations that are available cooling. Once a configuration is selected, the formulae

possible with the Pulse PA090X Planar Transformer Platform. and charts can be used to determine the approximate power

The package is typically capable of handling between 150-250W dissipation and temperature rise of the component in a given

NOTES:

1. The base PN (ie: PA0901) uses an ungapped core. The minimum primary inductance for any configuration can be calculated as:

Primary Inductance (µH Min) = 3.4 * (Primary Turns)²

2. The above base part numbers (PA09XX) are available from stock

3. It is possible to add a small gap to the transformer. Gapped transformers are non-standard and can be made available upon request,

but are not typically available from stock. To request a gapped version of the transformer, add a suffix “G” to the base number (ie:

PA0901NLG). The nominal inductance with a gap can be calculated as: Primary Inductance (µH Nominal) = 2.2 * (Primary Turns)²

Notes from Tables

1. The above transformers have been tested and approved by

Pulse’s IC partners and are cited in the appropriate datasheet

or evaluation board documentation at these companies. To

determine which IC and IC companies are matched with the

above transformers, please refer to the IC cross reference on

the Pulse web page.

component (ambient plus temperature rise) does not exceed

its operating temperature. To determine the approximate

temperature rise of the transformer, refer to the graphs below.

3. The “NL” suffix indicates an RoHS-compliant part number. Non-

NL suffixed parts are not necessarily RoHS compliant, but are

electrically and mechanically equivalent to NL versions. If a part

number does not have the “NL” suffix, but an RoHS compliant

version is required, please contact Pulse for availability.

2. To determine if the transformer is suitable for your application,

it is necessary to ensure that the temperature rise of the
